Introduction
A peptic ulcer is an open sore that develops in the lining of the digestive tract, most often in the stomach or the duodenum (the first part of the small intestine just past the stomach). It happens when the protective mucus lining is worn away faster than it can repair itself, exposing the tissue underneath to stomach acid and digestive enzymes. Peptic ulcer disease remains common in India, driven largely by how widespread H. pylori infection is, though NSAID use is an increasingly important second cause. At KAGE, peptic ulcers are diagnosed by direct visualization on endoscopy and treated based on their actual underlying cause — not simply managed with antacids indefinitely.
How common is peptic ulcer disease in India?
H. pylori infection is one of the most common chronic infections in India, with studies estimating prevalence between 60% and 80% of the population — among the highest rates in the world, and higher still in rural areas and lower socioeconomic groups, largely reflecting sanitation and household crowding during childhood, when the infection is most often acquired. Despite this very high infection rate, peptic ulcer disease itself is far less common: only an estimated 10–20% of infected people ever develop a symptomatic ulcer, with the rest carrying the infection without ever knowing it. When ulcers do occur, duodenal ulcers substantially outnumber gastric ulcers in Indian patients, and disease is most frequently diagnosed in the 40–59 age group.
Why doesn't everyone with H. pylori get an ulcer?
This is one of the most common points of confusion for patients who test positive for H. pylori. The outcome of an H. pylori infection depends on several factors beyond simply having the bacteria present: which strain is involved (some carry more aggressive genetic markers that increase ulcer risk), the specific pattern of inflammation it causes in the stomach, individual genetics, and other exposures such as smoking, alcohol, and NSAID use. This is exactly why testing positive for H. pylori doesn't automatically mean a peptic ulcer is present or inevitable — but it does mean eradication treatment is generally still recommended, both to resolve any current or future ulcer risk and because the infection is linked to broader long-term stomach health, including gastric cancer risk.
Types of peptic ulcer
| Duodenal ulcer | Gastric ulcer | |
|---|---|---|
| Relative frequency in India | Much more common | Less common |
| Pain pattern | Often eases with eating, returns 2–3 hours later or at night | Can worsen with eating |
| Typical cause | Strongly linked to H. pylori | H. pylori and NSAIDs both common causes |
Symptoms of peptic ulcer
- Burning or gnawing pain in the upper abdomen, often related to meal timing depending on ulcer type
- Bloating
- Nausea
- A feeling of fullness or discomfort after eating
- Heartburn-like symptoms
- Unintentional weight loss, in some cases
What causes peptic ulcer disease
- Helicobacter pylori (H. pylori) infection — the leading cause in India
- Long-term or frequent use of NSAIDs (common painkillers) — an increasingly significant cause, and can occur without H. pylori
- Smoking — both increases ulcer risk and slows healing
- Heavy alcohol use
- A high-salt diet, associated with increased risk in Indian studies
- Severe physical stress, such as critical illness or major surgery (stress-related ulcers)
- Family history of peptic ulcer disease
How peptic ulcer disease is diagnosed
- Upper GI endoscopy — the most direct way to visualize an ulcer and take a biopsy if needed, including to rule out malignancy in gastric ulcers
- H. pylori testing — breath test, stool antigen test, or biopsy-based testing during endoscopy
- Blood tests — to check for anemia if bleeding is suspected
Peptic ulcer treatment: a staged approach
- Step 1 — Confirm the cause: H. pylori testing and a careful review of NSAID or other medication use
- Step 2 — H. pylori eradication therapy if positive: current evidence favors quadruple therapy (combining multiple antibiotics with acid suppression) over older triple-therapy regimens, given meaningfully higher eradication rates and lower recurrence
- Step 3 — Stopping or switching the responsible medication, where NSAID use is the cause
- Step 4 — Acid-suppressing medication (PPIs) to relieve symptoms and allow the ulcer to heal, typically continued for several weeks
- Step 5 — Confirmation testing after treatment to verify H. pylori has actually been eradicated, and follow-up endoscopy for gastric ulcers to confirm healing and rule out malignancy
Possible complications if left untreated
Untreated peptic ulcers can lead to gastrointestinal bleeding, perforation (a hole through the stomach or duodenal wall, which is a surgical emergency), or, over time, scarring that narrows the digestive tract and causes obstruction. Perforation in particular carries a meaningful mortality risk in Indian clinical data, especially with delayed presentation — which is why the emergency symptoms above should never be dismissed as ‘just a bad stomach ache.’
Peptic ulcer care at KAGE
An ulcer and gastritis are treated differently, so the first step is establishing which is present and why — endoscopy with biopsy, or an H. pylori breath test where the question is infection rather than ulceration. Our gastroenterologists then re-test after eradication therapy instead of assuming it worked, since unconfirmed treatment is the usual reason ulcers return. To have symptoms or a positive H. pylori result reviewed, book a consultation.
Frequently asked questions
Not necessarily. Only around 10–20% of people infected with H. pylori ever develop a symptomatic ulcer. Treatment is still generally recommended if you test positive, both for current symptoms and long-term stomach health.
Yes, in most cases. Eradicating H. pylori or stopping the responsible medication, combined with acid-suppressing treatment, heals the large majority of peptic ulcers.
Current treatment typically uses a combination of two or more antibiotics with an acid-suppressing medication over 10–14 days. Confirmatory testing afterward verifies the infection has actually cleared.
Sudden, severe abdominal pain should be treated as a possible emergency — it can indicate a perforated ulcer, which needs immediate medical attention rather than waiting to see if it improves.
Diagnostic testing and standard treatment are generally covered under most health insurance plans; our team can help verify your specific coverage during consultation.
NSAIDs are usually stopped or switched during ulcer treatment. If you need long-term pain management for another condition, your doctor can discuss protective options rather than simply stopping treatment for that condition.
Spicy food, alcohol, and excess caffeine can worsen symptoms for some people, though diet alone doesn't cause or cure ulcers — treating the underlying cause is what matters most.
Everyday stress alone is not a primary cause, though severe physical stress — such as major illness, injury, or surgery — can cause a distinct type of stress-related ulcer, particularly in critically ill patients.
Most ulcers show significant healing within 4–8 weeks of appropriate treatment, though healing is confirmed with follow-up rather than assumed once symptoms improve.
Recurrence is uncommon once H. pylori is confirmed eradicated and NSAID use is addressed, but it can happen with reinfection or if the underlying cause isn't fully resolved — which is why confirmatory testing matters.
